DEVICE non Application filed Decembe1fl24, 1926.

My invention relates to the Couplings of railroad cars,

for holding the movable larly in devices jaws of such couplers in openthe ready reception of the improvements in and p articuposition forcoupling member of the other car, allowing a positive engagement of thecoupling clutches or members for the reception of the coupling boltsetc.

It is the principal object of my invention to provide a device of thissimple and therefore type of extremely inexpensive construction, whichyet is durable and efficient in its operation.

Another ob ect of the vision of a device of type invention is the pro-.the above described suitably formed by strong wire spring members forholding the movable jaws of the couplings in open position, wherebyeither one spring member or springs may be usec.

a plurality of such These and other objects and advantages of myinvention will become more fully apparent as the description thereofproceeds,

and will then be specifically defined in the appended claims.

ii the accompanying dr awing, forming a material part of thisdisclosure:

Fig. 1 is a plan View of a car coupling member having its movable jawkept in open position by a device constructed according to my invention.

Fig. 2 is a side view Fig. 3 is a view, similar thereof.

to Figure 1, of a nodified form of my device.

Fig. 4; is a side view thereof.

As illustrated in Figures bar of a coupler, designated 10, has

1 and 2, the draw an enlarged head 11 equipped with a stationary jaw 12,and a movable or the inner end of which is to the head by a pin swingingjaw 13, pivotally secured or bolt 14 having an outer head 15 andextending at both of its ends beyond the plane of the head.

A strong spring wire 16 'uided intermediate its ends about a in positionby means of a plate 18 and a nut 19 in engagement therebolt 17 and isheld pin or with and threaded upon the end of the bolt. The outer endsof the wire 16 are suitably bent and guided about the projecting ends ofthe pin or bolt 14, as indicated at 20 and 21, respectively, and the angularly bent 8X- or the like is HOLDING THE MOVABLE JAWS OF COUPLERSOPEN.

Serial No. 156,861.

treme ends of the wire 16, are designated 22 and 23 respectively andengage laterally into a bore 24L in the jaw 13 at opposite sides thereoffor a suflicientdistance.

It will be clear that the spring 16 will at all times hold the couplingjaw'13 open for the introduction of the coupling member of an adjoiningcar so that the coupling clutches may engage and be held in engagementby the customary coupling pin. As any of the customary coupling clutchesand pins may be used with my device, and as they do not form an objectof the present invention they need not further be specificallydescribed.

p In the modified form of my invention illustrated in Figures 3 and 1,two separate spring members 26, 27 are used for holding the movable jawof the coupling open, and have their ends wound about pins or bolts 28projecting from the head 11 and held in place by means of nuts 29engaging plates 30.

Intermediate their ends the springs are wound about the ends of a pin orbolt 14 headed at one end as at 15, and projecting beyond the head 11,as indicated at 81, 31 respectively. The extreme outer ends of thesprings 26, 27 are angularly bent as above described with respect to thepreferred form, and engage into a bore 24 of jaw member 13 at oppositeends.

The operation of my improved device for holding the swinging jaws of carcouplers open at all times will be entirely clear from the abovedescription, and it is to be understood, that such changes as comewithin the scope of the appended claims may be made in the constructionof my device without departure from the gist of the invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A device of the class described comprising a strong wire springhaving an iiitermediate bend, a bolt and nut for securing the spring atthe bend to the head of a coupler, a pin transversely held in thecoupler head having the spring wound about its ends, and means foranchoring the outer extreme angularly bent ends of the wire in theswinging jaw of the coupler for holding the same open.

2. A device for holding the swinging jaws of car couplings in openposition comprising 4, spring, a: pin in the head part of the couplingabout which said spring is wound intermediate its ends, a nut forholding the spring in position on said bolt, :1 cross-pin on saidcoupling head extending beyond the plane thereof about which said springis wound, said swinging jaw having a crossbore in which the ends of saidspring are anchored.
